Sylvain Luc (born 7 April 1965) is a French jazz guitarist.
He tours regularly but rarely appears in high-profile jazz festivals. He is particularly attracted to duets, but he has also been seen in trios (his own, plus Trio Sud, and on tour in 2009 with Steve Gadd and Richard Bona) and rarely with larger groups. His best-known works are the two duet albums with Biréli Lagrène, with whom he has toured many times.
